5.4.2.12. Unbalance
The selection of this option include on selected parameters list for recording the value of
NEG% and ZERO% s which are index of unbalance of input voltage signal respective to
negative tern and zero term (see § 10.8). “Unbalance” is not shown for single phase
systems.
5.4.2.13. Spike
This option permits to set the control parameters relative to recording of voltage fast
transients (spike) events (see § 10.9) with 5
s resolution which is completely independent
from periodic analysis (regulated by integration period). The below screen is shown by
meter:

Press F4 key (alternatively touch MODIFY at display) for setting the parameter for
detection and recording of voltage spikes. In particular is possible to set:
The value of voltage threshold to detection and recording the voltage spike event from
meter. This value s selectable from 100V and 5000V value.

1. Move the cursor using arrows keys on field relative to “Spike” , marked it with blue
background.
2. Use up or down arrow keys or press F3 or F4 keys (alternatively touch the MOD(+) or
MOD(-) s at display) to set the correspondent value. Pressing and holding of these
keys permit a rapid values setting, while the single pressure increase or decrease on
only unit the value.
3. Press SAVE or ENTER keys (or the smart icon ) to save each performed setting.
